perl-CGI-Ajax

A perl-specific System for writing Asynchronous web Apps

CGI::Ajax is an object-oriented module that provides a unique mechanism for using perl code asynchronously from javascript- enhanced HTML pages. CGI::Ajax unburdens the user from having to write extensive javascript, except for associating an exported method with a document-defined event (such as onClick, onKeyUp, etc). CGI::Ajax also mixes well with HTML containing more complex javascript. CGI::Ajax supports methods that return single results or multiple results to the web page, and supports returning values to multiple DIV elements on the HTML page. Using CGI::Ajax, the URL for the HTTP GET/POST request is automatically generated based on HTML layout and events, and the page is then dynamically updated with the output from the perl function. Additionally, CGI::Ajax supports mapping URL's to a CGI::Ajax function name, so you can separate your code processing over multiple scripts. Other than using the Class::Accessor module to generate CGI::Ajax' accessor methods, CGI::Ajax is completely self-contained - it does not require you to install a larger package or a full Content Management System, etc. We have added _support_ for other CGI handler/decoder modules, like the CGI::Simple manpage or the CGI::Minimal manpage, but we can't test these since we run mod_perl2 only here. CGI::Ajax checks to see if a header() method is available to the CGI object, and then uses it. If method() isn't available, it creates it's own minimal header. A primary goal of CGI::Ajax is to keep the module streamlined and maximally flexible. We are trying to keep the generated javascript code to a minimum, but still provide users with a variety of methods for deploying CGI::Ajax. And VERY little user javascript.
